To all whom t may concern:

Be it known that I, MARVIN H. J ESTER, a citizen of the UnitedStates ofAmerica, residing in the city and county of Denver and State ofColorado, have invented a newand useful Means for SupportingPlasterBoa-rds in Partition .Conitructiom of which the following isaspeci cation. v

My 1invention relatesto improvements in,

means 'for supporting plast-er boards, used in partition construe-tion.v f The object of the invention is to provide in connection with achannel' bar form of studding, a plurality ofy clips comprising Fig. 1.of a portion of the partition on the line 3 3 of Fig. 2. `Fig. 4 is aperspective View of,-

substantially Urshaped metal plates which are divided through theirVhorizontal base members and through one of their upright l .members soas to st-raddle a channel bar or.

partition showing plaster boards supported` by my improved supportingmeans. Fig. 2 is a horizontal sectional View of a portion of apartition-full size-.on the line2-2 of Fig. 3 is a vertical sectionalview one of the clips in engagement with a portion of a plaster board,the stud or .channel bar being shown in 'aroper relative position,

in dotted lines. Fig. 5 is an' edge view of one of the clips, showingthe ends or upright members bent slightly toward each other, said endsbeing sprungwhen the clip is applied. Fig. 6 is an end View of theclip-showing the divided member. Fig. 7 is a pers ective view showi fr achannel bar and. a

clip of the length required in forming a double portion, two setsofplaster boards and a companion clip being shown in dotted lines. Fig.8 is a vertical sectional View of a portion of a double partition.' Fig.9 is a' horizontal sectional `view thereof. Fig. 1Q is `a perspectiveView offaf modification in the function of two clips, and Fig. 11 is avview of the blank. from which the clip 10 is formed. Y

Referring to theaccompanying drawings:

The numeral 1 indicatesthe studs or up'-' rights, which'arepreferablymetal channel which a single clip is` arranged to perform` PatentedN0v.'11,1913. i.

'balTS of suitable dimensions, those'illustrated being three-fourths ofan inchwide by threef l .eighths of an inch deep andl of a length toextend from floor to ceiling, to which their respective ends are firmlysecured.

In Figs. l to et I lhave illustrated va single partition, o r one inwhich a single thickness of plaster boards is employed. In thisarrangement the boards are placed against one side only :of the channelbar, and theirv meeting ends or joints are' preferably arrangedinstaggeredl form., or 'so that those of each alternateyrow of boardsare in the same ver tical line, as clearlyshown in Fig. l, thisarrangement preventingthe formation of cracks along theA lengthl of thestuds after `the plaster has set.

The plaster,boardsx 2` are placed against `the channel bars inhorizontal rqws, one, row

above another, and are clamped to said bars by clips 3, which A,areformed as' follows:

Metal plates of suitable dimensions are employed, and the end portionsof each 'plate are bent'at right angles to its base. or main portion,the space between. the two bent 'ends corresponding to the width ofachannel bar and the thickness of a plasterA board, when the clips areused for single partitions; but

when lused -for a double partitiom'f as shown by Figsf to 9, the spacebetweenl'thefbent ends is the equivalent of the width of achannel barand two thicknesses of plasterlboard, as will be understood. Beforethefends of the plate are bent, however, a longitndinal .strip ofmetal,equal Vin width to the'diepth of the channel bar, is cut or stamped dutlof it, leaving a central slot or 'space 4, which extends from one end ofAthe Yplate to the point where the bend would occur adjacent to theopposite end of the plate. 4rIhe ends of the plate'aregthen bent atright angles lto its baseMas clearly shown by Fig. '4, to form asubstantially U-shaped clip, the base and one endlof which isi centrallydivided or slotted. The clips 'are'plaoed upon the channel bars so as tostraddle' them, as shown, the bar ,extendingthrough the slot 4, and thesolid undivided; end-y '5- Q-:I-the i Clip bearing horizontal edge of a.plaster board and engage its face, as will appear by reference to Fig.4.

\ In practice, the plaster boards are placed one above another againstthe channel bars,

in the mannen shown by Fig. 1, each board being secured before the nextboard is placed in position. Beginning with a bottom board, clips arefirst placed upon the two channel bars, to which the vboard is to besecured, with their ends extending upward, and before placing the clips,their ends are pressed by the operative so as to incline slightly towardeach other, as shown in Fig. 5. The lower edge of a plaster board isthen inserted between the upturned, divided ends 6 of the-clips, and theadjacentsides of the channell bars, and as the space between the ends ofthe clips, before they are pressed, corresponds to the width of achannel bar and the thickness of a plaster board, it will be seen thatthe edge of the plaster board must be forced in between the end of theclips and the channel b ars, and this springingof the ends of the clipswill cause them tolirmly grip or engagethe sides of the channel bars andthe surface of the plaster boards, so that the said boards will befirmly held in contact with the bars. Clips are next placed upon thebars so as to resupon the clipswhlch engage the upper edge of the board,their ends extending upward, so as to engage the lower edge of the nextboard, as'shown by Fig. 1, and thus the boards are secured 'untiltheyextendfronifloor to oeiling, the ends of the boards ineachalternate row.being in the same rvertical line, in order to break the joint along thechannel bar, as before mentioned.. l

In Figs. 7 to 9 I haveshown a double partition,ifo'r one in whichplasterboards are securedt both vsidesof the channelbars. The clip 7used in the double partition, is

Videntical with that used inf the single parti:

- tion, excepting as to length, the clip 7 being long 'enough to clampboards on opposite sides of the bars, as shown. v

Iii-Figs. l0 and 1I is illustrated a twin or double clip, 8, which isadapted to take the place of two such clips as are shown in-the otherviews. This clip is made from a plate of suitable dimensions, -whiehy isalso slotted or` divided as shown at 9,'so as to straddle 'the channelbars in'like manner as the clips 3 and 7. To vforni the boardengagingmembers of thisiclip, its. opposite end-portions are each formed-'withtwo parallel slits l0,

which extend from the edges of the plate to the'points 11, where theright angle bends are formed. The slits on each side of the plate are inline, and are midway between the edges of the slot 9 and the side edgesof 65 the plate. The slits at one end of the plate or blank form outerlingers 12 and inner fingers 13, the inner fingers being bent at rightangles to the plate in one direction, while the outer fingers 12 arebent at right 70 angles to the plate and in the opposite direction tothe fingers 13. The slits at the opposite end of the blank form outerfingers 14, which are bent at right angles to the plate, and in the samedirection as the lingers 13, while the portion 15 between, is bent atright angles and in the opposite direction to the lingers 14. Inpractice, these clips are placed astride the channel bars in like manneras theclips 3 and 7, their base or main 80 portions lying between thehorizontal edges of two boards, and their fingers clamping to the boardsagainst the sides of the channel bars, as willtbe understood. This clipmay be used either for single or double partitions. Afterthe plasterboards have -been secured to the studding, the usual rough and finishingcoats of plaster are vapplied to opposite sides of the boards, as shownby dotted lines, Fig. 2, y

The clip' herein described is not only extremclyV simple and thoroughlypractical, but it eliminates the key or wedge necessary in clips forplaster boards in present use; Y

While I have illustrated the clip in oonnection with partitionconstruction, it should be understood that it is equally well adaptedfor ceiling construction also.

-Iaving described my' invention, what I 100 claim as new and desire tosecure by Letters Patent, is.:

1. In a supporting device for plast-erboards, a stald, and a.clamping-plate coniprising a horizontal portion and right-angle endportions adapted to secure plasterboards to said. stud, said horizontalportion and one of said end portions being slotted to permit saidclamping-plate to straddle the stud.

'2. In a 'supporting device for plasterboards, a stud, and aclamping-plate comprismg a horizontal portion and right-angle endportions divided and bent to form op 3ositely projecting lingers-adaptedto secure MARVINl H. J ESTER.
